A filter/strainer basket for use with a fluid pump has a base and side wall; a portion of the side wall is concaved and traverses the full height of the basket such that in use the filter basket is stepped away from the outlet pipe and such that in use a concaved portion extends upward from the bottom of outlet pipe side of the basket and terminates at the top of the outlet pipe side of the filter/strainer basket at the rim. The basket may be of unitary non-metallic (e.g. plastic) construction; it may comprise a biocide material to combat algae, fungal and biomaterial build-up. For example, a device comprises inlet pipe 4, outlet pipe 5, filter basket 2, filter basket holder 1 and convex/concave tube filter/strainer 3. The device may be used as an inline filter / strainer for fluid pumps; it may be less prone to blockages due to the enhanced surface area of the convex filter portion. |
